Subject: [WiX-users] error when executing custom action
Hi:
I've got the following custrom action and property defined:
<!--Property Definitions.-->
<Property Id="OLDSCHEMEINSTALLER">
<RegistrySearch Id="OLDSCHEMEINSTALLER"
Root="HKLM"
Key="Software\Microsoft\Windows\CurrentVersion\Uninstall\Andre Louis 44.1K
sound Scheme 1_is1"
Name="QuietUninstallString"
Type="raw" />
</Property>
<!--Custom action definitions.-->
<CustomAction Id="UninstallOldScheme"
Directory="INSTALLDIR"
ExeCommand=[OLDSCHEMEINSTALLER]
Return="check" />
When I try to execute this in the installExecute sequence, I get windows
installer error 1721.
Any ideas why this is happening?
Cheers
Sean.
